Disclosed herein is an intrinsically self-healing composite based upon in situ thermal remendability of an embedded polymeric interphase. The fiber-reinforced composite (FRC) material may incorporate a thermoset polymer with a defined glass transition temperature (T.sub.g) and/or a thermoplastic material of amorphous or semi-crystalline nature. The polymeric interphase can be incorporated as a plurality of particles, fibers, meshes, films, or 3D-printed structures. The self-healing composite includes a resistive heating component as a structural element that minimizes electrical energy demand and impact on mechanical integrity. Healing occurs in situ via resistive heating and can be enabled below, at, or above the glass-transition temperature of the FRC matrix, demonstrating viability for in-service repair under sustained loads. In addition to providing rapid healing functionality, the polymeric interphase increases inherent resistance to interlaminar fracture. Repeated heal cycles have been achieved in a double cantilever beam (DCB) fracture test without significant degradation in performance.

A method of forming a sloped roof can comprise obtaining a base layer comprising at least one of a permeable mesh, woven fabric, non-woven fabric, plastic, foam material or combinations thereof; applying the base layer over a roofing substrate of the sloped roof; and applying a liquid roofing material to the base layer to form a liquid applied roof.

Embodiments of a vehicle interior system and methods for forming the same are disclosed. A glass substrate is bent to a curved shape within a mold cavity, and a liquid polymer material is delivered to the mold and is in contact with the curved glass substrate. The liquid polymer is solidified to form a polymer frame that engages the bent glass substrate, and the engagement between the frame and the glass substrate holds the glass substrate in the bent shape. The temperature of the glass substrate during the bending process and formation of the frame are maintained below the glass transition temperature of the glass substrate.
